后台動態添加的button，需要在Page_Load或者Page_Init重新動態生成才能執行button_click
public Panel GetContrlType()
{
Panel panel = new Panel();
Button btnsearch = new Button();
btnsearch.Text = "查詢";
btnsearch.ID = "btnsearch";
btnsearch.Click += new EventHandler(btnseach_Click);
panel.Controls.Add(btnsearch);
}
return panel;
}
protected void Page_Load(object sender, EventArgs e)
{
try
{
Button bsearch = PanelWarp.FindControl("btnsearch") as Button;
(Panel.FindControl("panel") as Panel).Controls.Add(bsearch);
bsearch.Click += new EventHandler(bsearch_Click);
}
catch (Exception ex)
{
throw ex;
}
}
protected void bsearch_Click(object sender,EventArgs e)
{
}
而且在Page_Load若使用if (!IsPostBack)，重新加載頁面后動態生成的控件會消失
